10 Appliances You Should Never Plug Into an Extension Cord

Extension cords are a convenient solution for powering multiple devices simultaneously. However, not all appliances are suitable for connection to these cords due to safety concerns. In this article, we’ll explore the reasons why certain appliances should never be plugged into extension cords and explore safer alternatives.

  1. Refrigerators:
    • Explanation: Refrigerators demand consistent power, and extension cords may not provide the stability required, risking damage to the appliance and increased energy consumption.
    • Safer Option: Directly connect to a wall outlet with a dedicated circuit.
  2. Microwaves:
    • Explanation: Microwaves generate intense heat and require a direct power source to function efficiently. Extension cords can compromise their performance and pose safety risks.
    • Safer Option: Use a wall outlet with the correct voltage.
  3. Air Conditioners:
    • Explanation: Similar to space heaters, air conditioners draw significant power and should be directly connected to avoid overloading extension cords.
    • Safer Option: Connect directly to a designated circuit.
  4. Washing Machines:
    • Explanation: Washing machines, with their variable power needs, can strain extension cords, affecting their performance and safety.
    • Safer Option: Plug into a nearby wall outlet with an adequate power supply.
  5. Dishwashers:
    • Explanation: Like washing machines, dishwashers require consistent power and should be connected directly to avoid potential hazards.
    • Safer Option: Utilize a dedicated wall outlet.
  6. Coffee Makers:
    • Explanation: Coffee makers, though seemingly harmless, can draw significant power during operation. The direct connection ensures safety and optimal performance.
    • Safer Option: Plug into a wall outlet with the appropriate voltage.
  7. Toasters:
    • Explanation: Toasters can be power-intensive, especially in larger models. Connecting them directly reduces fire risks associated with overloaded extension cords.
    • Safer Option: Utilize a wall outlet with a sufficient power supply.
  8. Hair Dryers:
    • Explanation: Hair dryers draw substantial power and should be connected directly to prevent overloading extension cords and potential fire hazards.
    • Safer Option: Plug into a wall outlet on a dedicated circuit.
  9. Water Heaters:
    • Explanation: Water heaters are high-power devices that draw a substantial load during operation. Plugging them into extension cords can lead to overheating, increased energy consumption, and pose fire hazards.
    • Safer Option: Connect water heaters directly to a dedicated wall outlet with the appropriate voltage and amperage.
  10. Electric Stoves:
    • Explanation: Electric stoves demand significant power for cooking, and extension cords are not designed to handle such loads. Using extension cords for electric stoves can result in overheating and safety risks.
    • Safer Option: Install electric stoves directly into a designated circuit with the necessary power capacity to ensure safe and efficient operation.


Prioritizing safety is very important when dealing with electrical appliances. By understanding the limitations of extension cords and adopting safer practices, individuals can mitigate potential risks and ensure the longevity of their appliances. High-power appliances should be treated with caution when it comes to electrical connections. To maintain safety standards and ensure optimal performance, avoid plugging these appliances into extension cords. Instead, prioritize direct connections to dedicated wall outlets, following manufacturer recommendations and electrical codes. By adopting these practices, individuals can safeguard their homes and appliances from potential risks associated with improper electrical setups.
